Why are Mn2+compounds more stable than F | Class 12 Chemistry Chapter The d-and f-Block Elements, The d-and f-Block Elements NCERT Solutions

Question:

Why are Mn²⁺compounds more stable than Fe²⁺ towards oxidation to their +3 state?

Answer:

Electronic configuration of Mn²⁺is [Ar]¹⁸ 3d⁵.

Electronic configuration of Fe²⁺is [Ar]¹⁸ 3d⁶.

It is known that half-filled and fully-filled orbitals are more stable. Therefore, Mn in (+2) state has a stable d⁵configuration. This is the reason Mn²⁺shows resistance to oxidation to Mn³⁺. Also, Fe²⁺has 3d⁶configuration and by losing one electron, its configuration changes to a more stable 3d⁵configuration. Therefore, Fe²⁺ easily gets oxidized to Fe⁺³oxidation state.
